In that case you should be able to make an extension out of the modules tar archive that will use much less ram.

Code: [Select]
mkdir /tmp/pkg
cp modules.tar.gz /tmp/pkg
cd /tmp/pkg
sudo tar xf modules.tar.gz
cd ../
sudo mksquashfs pkg/ modules.tcz

The edid data might be available under /sys/class/drm.

Otherwise you might need to compile edid-decode or read-edid.

Yes i had to compile edid-decode from  http://archive.ubuntu.com/ubuntu/ubuntu/pool/universe/e/edid-decode/

and i get the serial number like you said:

Code: [Select]
sudo find / -name "edid"

edid-decode /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/edid
